This Lens Cover for the Sigma 120-300mm f/2.8 DG OS HSM Sports Lens in digital camo from LensCoat is a 100% closed-cell neoprene cover that protects your lens from scrapes and bumps, helping to preserve its resale value. It also provides a thermal barrier during cold weather and provides protection from wet and inclement conditions. This cover can also break up the shape of your lens, making it less visible to wildlife.

A clear plastic window allows you to access the AF controls and the distance scale, while an orientation hole for viewing the dot indicator allows you to mount the lens on your camera without removing the cover.
